About
The Sich-3-R is an Earth radar observation satellite developed by Yuzhnoye SDO that will obtain high-resolution radar images of the Earth’s surface regardless of lighting conditions and weather, enabling all-weather, day-and-night Earth observation capabilities critical for disaster monitoring, maritime surveillance, and national security applications. Weighing 1,800 kg and operating in a morning-evening sun-synchronous orbit at 450 km altitude, it features a two-band (X-band and L-band) synthetic aperture radar payload achieving up to 0.5 meter resolution in X-band spotlight mode. The attitude control system achieves 0.05 degree pointing accuracy with plus or minus 60 degree roll angle capability, enabling wide coverage across multiple swath modes. An ammonia propulsion system enables orbital corrections over the 7-year design lifetime.
